You are making it seem like this is a new problem. And it isn't.

Centuries back it was weavers who were displaced by the industrial revolution and automated spinning machines. Coal mining went unfashionable from the late 1970s onwards and miners had to find new work. Industry in the US closed up shop and moved to China. These are just three examples of workers being made redundant in their then capacity. Two out of these three went by without much loss of life, the majority of the workforce found new jobs over time, and only some of them were screwed on a more permanent basis. Unfortunately, that's the shitty bell curve of these changes. But another thing that's been proven again over time is that we always think these miners or these factory workers are completely unhireable and it turns out the majority isn't. People thought MS Excel would eradicate the entire bookkeeping profession. And they are still around and I think actually grew in numbers because they are free from pencils and calculators and could do more interesting stuff instead. Don't fall for the so-called AI will replace everything talking point. The people who say this are either invested in so-called AI companies or drank the koolaid. All we hear for the moment is how theses models do a good a lot of the time and then break catastrophically bad somewhere. Humans still need to have a look for the time being. And thus a new job is born: chAIperone.

The problem these days is how the state responds to massive shifts like that. Social security nets have a finer mesh in the developed world outside the US. It's much easier to go from no job to living in a car to living under a bridge in the US. A lot of people in this thread call for UBI, which is sensible but isn't even likely in the more socialist Europe. UBI is a good answer though. Education is another one, e.g. free training programs or college classes for long term unemployed. None of that seems likely under 47.
